a 3-millimeter diameter droplet of heptane fuel burns in microgravity, producing soot.


Published June 21, 2011


Fuels burning in space behave very differently than they do on Earth because of the absence of gravity. The Flame Extinguishing Experiment (FLEX) examines the combustion of liquid fuel droplets on the International Space Station. In this image, a 3-millimeter diameter droplet of heptane fuel burns in microgravity, producing soot. When a bright, uniform backlight is placed behind the droplet and flame and recorded by a video camera, the soot appears as a dark cloud. Image processing techniques can then quantify the soot concentration at each point in the image. This colorized gray-scale image is a composite of all the individual video frames of the backlit fuel droplet. The bright yellow structure in the middle is the path of the droplet, which becomes smaller as it burns. Initial soot structures (in green) tend to form near the liquid fuel. These come together into larger and larger particles which ultimately spiral out of the flame zone in long, twisting streamers. A plane of symmetry has been added for effect. Image Credit: NASA
